    Bad motor mounts allow the engine to move forward under hard braking.

    BMW put a limiter in place that attaches to the bottom of the bellhousing and hits the subframe to prevent this from happening when the engine mounts fail, but the rubber damper on the limiter is typically missing, allowing the fan to ruin the radiator.

      I suspected that may have been the case. I should probably still fix this so the water pump doesn't destroy my new fan. Thanks for the insight!​

        Yup, I definitely wouldn't do another autox without doing engine/trans mounts.

        The stopper/limiter is 11811132177​ and the rubber buffer for it is 11811132527 BTW. May be worth inspecting/replacing what you don't have while you're down there. ​​
